25 years ago, a pending closure of the Molson brewery was almost the end for a brewery full of people. But, where some people see the end, others…Read More
It starts with the finest ingredients and ends with the bottom of your glass
The basic ingredient in beer is barley malt. Malt is barley grain that has been allowed to germinate and age. The barley grain is then is kiln-dried to halt further germination, giving brewmasters the perfect base for the world’s oldest and most loved alcoholic drink.
In the mashing process, the malt is blended with brewing water in a “mash mixer” where it is then heated according to a brand-specific, time-temperature program. During this process, malt starches are converted into fermentable and non-fermentable sugars by natural enzymes.
Mash is transferred to a lautering (our fancy way of saying straining in the brewing world) vessel. Hot water is flushed over the mash separating the sugars from the grains. A sweet liquid called “wort” drains through and runs off into the brew kettle.
Then we start boiling and hopping. The brew kettle, holding up to 5,000 gallons and made of stainless steel is probably the most recognizable sight in a brewery. The wort boils in the brew kettle under carefully controlled conditions. Boiling serves three functions: to sterilize, to concentrate the wort to the desired alcohol content, and to get the desired flavor from the hops.
After the wort has taken on the flavor of the hops, it is passed through a hot wort tank where a lot of the protein—which was created during boiling—is removed. Then the brews go through a heat exchanger where they aerate and cool to fermentation temperature.
Where the magic happens. Wort is moved to the fermenting vessels and yeast is added. The yeast metabolizes the sugar in the wort and breaks it down into carbon dioxide and alcohol. The carbon dioxide is collected, cleaned, liquefied, and stored until it’s added back to the beer to give it the refreshing carbonation we all know and love. Fermentation lasts approximately nine days. Finally, we have beer!
At this stage, the beer gets a chance to relax and mature. This is where we extra-age it for the smoothest taste. When it’s ready, the beer is carbonated, clarified by filtration and transferred to tanks for bottling and canning.
To package the beer, returned empty bottles from the beer stores are cleaned, sanitized and inspected. During packaging we fill about 300 bottles per minute and 500 cans in the same amount of time.
This is where the most popular job at the brewery steps in. The beer is taste-tested by specially trained testers and examined by quality control personnel in our laboratories. This is done at every stage of production to ensure that the beer meets the high quality standards we’ve set.
